Wall Loads in Squat Steel Silos during Earthquakes
Silo behavior during earthquakes may be of two kinds. Elevated silos may respond in a manner similar to elevated tanks, displaying the characteristics of a large mass inducing inertia loads in a stiff supporting structure. By contrast, the walls of squat ground-supported silos are subject to significant wall loads from the stored mass. The paper is concerned only with the latter category, which has received little attention to date. A cylindrical silo structure containing bulk solid is modelled using an elastic finite element analysis for solids with axisymmetric geometry, and the earthquake loading is represented by a quasi-static horizontal body force. The stress patterns in the bulk solid and the loads exerted on the silo walls by the earthquake are deduced.
